无法打开扩展控制文件 citext.control

Question

环境

Ubuntu 20.04 和 Debian 10，分别为 Python 3.8 或 3.7。

Postgresql 版本 11、12 和 14 已试用。

Psycopg2-二进制 2.8.6

概览

我正在尝试安装 Django 项目，但出现此错误：

psycopg2.errors.UndefinedFile: could not open extension control file "/usr/share/pgsql/extension/citext.control": No such file or directory

psycopg 开发人员告诉我这可能是 postgresql-contrib 库的问题。同样，其他人已经能够fix this error by installing postgresql-contrib，但是，这对我不起作用。我也试过安装 postgresql-12.

我可以看到 citext.control 在 /usr/share/postgresql/12/extension/citext.control 中可用，所以我尝试 ln -s /usr/share/postgresql/12 /usr/share/pgsql 没有效果。

我也在Postgres中运行CREATE EXTENSION citext;，同样没有效果。

非常感谢对此的任何支持，因为我希望这个项目已经上线！

非常感谢。

Answer 1

您是否尝试过从打包系统安装 python3-psycopg2？

我的 Ubuntu 20 安装程序安装了这个，并且 postgresql 连接与 django 一起工作。

ii python3-psycopg2 2.8.4-2 amd64 Python 3 module for PostgreSQL

Answer 2

我在本地 Django 服务器上安装了 postgresql-contrib，而不是在远程数据库服务器上。在与 Postgresql 相同的服务器上安装解决了这个问题。
